Landscape Maintenance Ultimate Guide to Hydrangea Care September 25, 2024 Hydrangeas are a popular choice for Texas gardeners for their stunning blooms and variety of species. Whether you are an experienced gardener or a novice, understanding how to care for hydrangeas is essential to maintaining their beauty. In this guide, we’ll cover everything you need to know about hydrangea care, including planting, maintenance, and seasonal care. Why Hydrangeas Grow Well in North Texas Hydrangeas are well-suited to the climate and soil conditions in North Texas. The region’s hot summers and usually mild winters allow for a variety of hydrangeas to thrive. However, due to the intense summer heat, it is crucial to provide some afternoon shade and ensure regular watering to keep the plants healthy. They are perennials and return each year with proper care and can live for many years, providing beautiful blooms season after season. Popular Types of Hydrangeas Oakleaf Hydrangea Oakleaf hydrangea features large, oak-shaped leaves and cone-shaped flower clusters that bloom in white and gradually turn pink. This hydrangea is particularly admired for its striking fall foliage, which turns shades of red, orange, and purple. Oakleaf hydrangeas are drought-tolerant and perform well in hot summers, making them a suitable choice for North Texas. They do require regular watering, especially in the first year to establish roots. Limelight Hydrangea Limelight hydrangea is known for its bright, lime-green blooms that fade to pink and burgundy in the fall. This variety can grow up to 8 feet tall and wide and is renowned for its sturdy stems that support the large flower heads without drooping. Limelight hydrangeas thrive under full to partial sun and can tolerate some drought conditions once established. Prune in late winter or early spring to promote vigorous growth and flowering. Climbing Hydrangea Climbing hydrangea is a unique vine that can grow up to 50 feet tall, ideal for covering walls, fences, and trellises. It produces fragrant white flowers in late spring to early summer. While it takes a few years to establish, once it does, it requires minimal care. This hydrangea prefers cooler, shadier spots, so in North Texas, it should be planted in areas protected from the harsh afternoon sun. Endless Summer Hydrangea Endless Summer hydrangea is a popular variety known for its ability to bloom on both old and new wood, providing flowers throughout the growing season. The blooms can be blue or pink, depending on the soil pH. This hydrangea is heat tolerant but benefits from some afternoon shade. It prefers morning sun and afternoon shade. Smooth Hydrangea Photo Credit: The Spruce Smooth hydrangea, also known as Annabelle, produces large, round white flower heads that can grow up to 12 inches in diameter. This hydrangea is easy to care for and can tolerate a range of conditions, making it a versatile choice. It is known for its cold hardiness and adaptability. This variety prefers partial shade but can tolerate full sun with adequate moisture. Planting Hydrangeas The best time to plant hydrangeas is in the Fall before the first frost or in Spring after the final frost. They thrive in well-drained soil with plenty of organic matter. When deciding where to plant hydrangeas, choose a location with morning sun and afternoon shade. Hydrangeas can tolerate full sun in cooler climates, but in hot summers, they benefit from some shade. How to Plant a Hydrangea Planting hydrangeas is straightforward: Dig a hole that is twice as wide as the root ball and just as deep. Place the root ball in the hole, ensuring the base of the plant is level with the ground. Fill the hole with soil, water thoroughly, and add mulch to retain moisture. How Far Apart to Plant Hydrangeas The spacing of hydrangeas depends on the variety. Generally, space them 3 to 10 feet apart to allow for proper air circulation and growth. For smaller varieties like Little Lime hydrangea, 3 to 4 feet apart is sufficient. Hydrangea Care Watering and Sunlight Hydrangeas need regular watering, especially during dry spells. The soil should be consistently moist but not waterlogged. While most hydrangeas prefer morning sun and afternoon shade, some varieties can tolerate more direct sunlight. Pruning Hydrangeas Pruning is essential for maintaining the shape and health of hydrangeas. Varieties that bloom on new wood, such as Limelight and Endless Summer, should be pruned in late winter or early spring. Those that bloom on old wood, like oakleaf hydrangea, should be pruned after flowering. Soil Amendments Hydrangeas benefit from soil amendments to maintain their health and vigor. Adding organic matter, such as compost, improves soil structure and fertility. For blue hydrangeas, amending the soil with aluminum sulfate can help maintain their vibrant color. How to Propagate Hydrangea Plants Propagating hydrangeas is a rewarding way to expand your garden. The most common method is through cuttings. In early summer, take a 6-inch cutting from a healthy hydrangea plant. Remove the lower leaves, dip the cut end in rooting hormone, and plant it in a pot filled with moist soil. Keep the cutting in a shaded area and water regularly until roots develop. Growing Hydrangeas in Pots Growing hydrangeas in pots is ideal for small gardens or patios. Choose a large pot with drainage holes and fill it with a high-quality potting mix. Ensure the pot is placed in a location with adequate sunlight and water the plant regularly. Potted hydrangeas may need more frequent watering than those planted in the ground. Contact Southern Botanical Hydrangeas are versatile and beautiful plants that can enhance any garden.
